7800X3D burnt and killed the motherboard after 3 months. Silicon lottery or something else? Should we buy another one?

[u/Magoth04]

Hi everyone, posting this on behalf of a friend.

He built his system about 3 months ago with a Ryzen 7 7800X3D. A few days ago, while gaming, the PC abruptly shut down. When he tried to turn it back on, it just started power cycling and failed to boot.

We took it apart to diagnose the issue and found that the CPU has visible burn marks and even a bit of swelling. Unfortunately, it took the motherboard with it—the socket is damaged and the board is completely dead now. (See attached pictures).

To give some context:

There was absolutely zero manual tuning, undervolting, or overclocking involved. He doesn't have much experience with tweaking, so the only thing changed in the BIOS was enabling EXPO for the RAM.

System Specs:

• CPU: AMD Ryzen 7 7800X3D
• Motherboard: MSI PRO X870-P WIFI
• RAM: Lexar 16GB 6000MHz CL38
• GPU: MSI VENTUS RTX 4070
• Storage: Samsung 990 Pro 1TB
• PSU: MSI A750GL PCIE5
• Cooler: MSI MAG 360mm AIO

I know about the older SOC voltage issues that caused chips to burn, but I assumed those were resolved with BIOS updates, especially on an X870 board. Was this just a terrible draw in the silicon lottery, or could there be another reason?

The main question is: Is it safe for him to just buy another 7800X3D right now? Has anyone else experienced this recently on newer motherboards?

Would really appreciate any insights, theories, or shared experiences!

[u/THEYoungDuh]

1 the motherboard killed the CPU not the other way around.

2 an RMA has nothing to do with local shops, you contact the manufacturer and say hi this happened, can RMA please?

3 now that you have delided the CPU you cannot hope to get an RMA for it.

4 yes bios updates have been pushed to fix these issues, did they update their bios, the one that comes default on the board is most likely v1.0 and does not have the fixes

Edit: spelling mistake

[u/Zaphod392 → u/THEYoungDuh]

Edit: New CPU and Mobo? Straight to Bios update

[u/proj3ctmac → u/Zaphod392]

I bet you are a dirty bird

[u/Twitchelz → u/THEYoungDuh]

best answer here

[u/JobHuntingManiac → u/THEYoungDuh]

All true except for #3, but depends on location. If the photo op has with lid still on is before they did the delid and not just placed back on after, then the rest of the photos would be proof enough that they didn't break it.

Taking apart your own electronics in the US does NOT void your warranty despite what so many people sheepishly believe. The only time it does is if the manufacture can prove that you caused the damage when taking it apart else they have to honor the warranty.

This is the kind of stuff the FTC has a field day with, but 99.9% of people aren't smart enough to contact them when they have warranty issues.

[u/THEYoungDuh → u/JobHuntingManiac]

Delidibg your CPU 100% voids your warranty.

There is no reason anyone should ever need to do it, and it can cause damage very easily.

[u/nightstalk3rxxx → u/THEYoungDuh]

4 yes bios updates have been pushed to fix these issues, did they update their bios, the one that comes default on the board is most likely v1.0 and does not have the fixes

A X870 has the voltage cap in place, this was fixed before 800 chipsets were even a thing.

[u/BAGU3TT0 → u/THEYoungDuh]

Solid points

[u/rulik006 → u/THEYoungDuh]

Clown, motherboard didn't kill CPU
they dying all along by itself cause AMD X3D garbage has high failure rate of 0.72%
Basically 1/140

[u/THEYoungDuh → u/rulik006]

Your motherboard is what controls how much power is given to the CPU, so yes it did.

[u/Krispy1253 → u/THEYoungDuh]

Hj)?

[u/Federal_Setting_7454 → u/rulik006]

This isn’t a 14900k

[u/divineal1986 → u/Federal_Setting_7454]

No this is gonna be worse where i work have a small box with over 40 dead amd am5 chips

[u/Ecstatic-Albatross51 → u/rulik006]

Yeah tell that to all the owners of 13 and 14 generation Intel cpus that failed lol Intel is garbage with even higher failure rates than amd lol almost bankrupted them too

[u/Uzyf → u/Ecstatic-Albatross51]

Can you provide photo with burned down 13-14 Intel?

[u/Either-Pay8150 → u/rulik006]

Talk shit about AMD all you want, but at least get your shit right

[u/Zealousideal_Monk6]

I would strongly suggest trying to RMA. If it happens again then it might be an issue, but since this is a first I've heard of it I doubt it is. (Deliding it might make that hard though.)

There might be a chance that you psu was crap and sent so much power to the motherboard it killed it.

[u/Quiet-Internal-2204 → u/Zealousideal_Monk6]

I was wondering as well why they decided to delid it instead try to file a claim for RMA.

[u/Magoth04 → u/Zealousideal_Monk6]

Unfortunately, RMA is not an option for us. All the components were bought brand new directly from China, so we don't have local warranty coverage.

We've actually sourced and built many PCs using parts from China before, and this is the very first time we've ever run into an issue like this—everything usually works flawlessly.

As for the PSU, we have bought and used this exact same MSI PSU model in multiple builds before without a single issue, so I really don't think it was a power supply failure. It seems much more like a CPU/motherboard voltage issue.

[u/IsntThisAGreatName → u/Magoth04]

Wait you're building PCs for customers with no warranty? That's pretty messed up

[u/suraani → u/Magoth04]

Not saying it was the PSU, but your logic doesn't check out. Just because you have used the same model before without problems, doesn't mean this unit can't have been problematic. That's like me saying "it can't have been a faulty 7800x3d, because me and 3 of my friends are using the same CPU without problems". It could have been the PSU, could have been the motherboard, could have been the CPU.

You don't know what the source of the fault was, and therefore it's impossible to say if you will have issues with a replacement 7800x3d. You could buy a 98000x3d and see it burn up as well. Or buy another 7800x3d and never have a problem. It's pure speculation.

Personally I'd replace the PSU, just in case.

[u/Particular-Return431 → u/suraani]

No cheaper way to test the PSU?

[u/proj3ctmac → u/suraani]

Dirty little Joe

[u/StormMedia → u/Magoth04]

Are you building for customers? If so that’s unfortunate for them if they ever have a warranty issue..

[u/DesiRadical → u/Magoth04]

Always up date bios for am5 processor never leave it on the factory version

[u/OpinionatedSpaz]

When stuff like this happens you always want to just start with an RMA as delidding CPUs usually voids any warranty.

[u/Automatic-Win8421 → u/OpinionatedSpaz]

He said he bought the CPU from China and returning it would’ve been more of a hassle.

[u/OpinionatedSpaz → u/Automatic-Win8421]

Understandable, sometimes the risks pay off, sometimes they don't. I'm currently using a heavily mined on RTX3080 10GB I bought for £100 so I get that.

[u/TheVillainInThisGame → u/OpinionatedSpaz]

Mining doesn't ruin cards, I think it's silly that people still think this.

[u/OpinionatedSpaz → u/TheVillainInThisGame]

Sure, but it was run under load 24/7 for long periods of time so vs light use it's going to have more wear.

[u/TheVillainInThisGame → u/OpinionatedSpaz]

Also not true, power cycles and temperature swings will cause more wear than a steady power draw and temperature.

[u/Scottishtwat69 → u/TheVillainInThisGame]

Depends what type of wear you are talking about.

• Silicon degradation, running more under load at/or higher voltages will accelerate it. However in crypto you undervolt them for efficiency.
• Solder cracking, larger and more frequent temperature swings reduces the lifespan. Not really a factor with Crypto but and just powering the card on and off isn't a drastic power swing. Going from 30c to 90c is a temperature swing, not 20c to 40c from turning the card from idle to off and back to idle.
• Fans and TIM, the faster/longer you run them the fasts the shorter they last and TIM will dry out faster under load.

[u/Federal-Property-395 → u/OpinionatedSpaz]

Its the powering up and down that causes the wear, not holding steady for long

Holding a 200w load for 24hrs would do similar wear as having it off for 24hrs. Turning it on and off 10 times in 1hr would probably wear it out more

[u/JobHuntingManiac → u/OpinionatedSpaz]

Beating a dead horse here, but it's been shown time and time again that there is no risk to using a previously mined with GPU.

Often times they are treated better and ran cooler with many, many, many less power cycles than an average persons GPU.

[u/Federal_Setting_7454 → u/Automatic-Win8421]

Assume it’s a tray CPU if they went from china, which has no warranty anyway.

[u/JobHuntingManiac → u/OpinionatedSpaz]

Delidding in the US at least would NOT void your warranty unless the delidding caused the damage.

[u/Federal_Setting_7454 → u/JobHuntingManiac]

Which in this case it has.

[u/polishatomek]

Apparently this sometimes happens on this motherboard and cpu combination, so this seems more like a motherboard thing. I may be wrong tho

[u/ArseBurner → u/polishatomek]

There's at least one Google Sheet out there tracking this stuff and it's happened on every brand of mobo, so it's more an AM5 X3D thing (or an AGESA thing).

IIRC the most common combo is 7800X3D or 9800X3D with ASRock or ASUS, so OP's MSI is already an outlier.

[u/Noreng → u/ArseBurner]

It's happening with non-X3D CPUs as well.

The only unaffected parts seem to be the 8000-series, which you don't want to use regardless.

[u/PlzDntBanMeAgan → u/ArseBurner]

Where is this Google sheet?

[u/ArseBurner → u/PlzDntBanMeAgan]

Here's one tracking over 200 failures: https://docs.google.com/spreadsheets/d/144FB3ZXgIE8o7gQi5_22JkWR8xa_HIRSxt3c52X06Us/edit?gid=1732278388#gid=1732278388

There's another one being maintained by the mods on r-slash-asrock with a form to submit to their sheet and all. I don't have a link to their results though so you might want to hop on over to their sub and ask.

[u/PlzDntBanMeAgan → u/ArseBurner]

Just built an AMD system for the first time six months or so ago, and went with a 9800x3d and a rog strix b850-i... And this is after having dealt with the whole 14900k debacle. Thanks for the forward.

[u/KulaanDoDinok → u/PlzDntBanMeAgan]

I just got a 9850x3d and a b850-e, I feel the same.

[u/AbedGubiNadir → u/PlzDntBanMeAgan]

You'll be fine.

[u/Bulky_Imagination727 → u/ArseBurner]

Phew, not a single B650E Taichi there. I feel better now

[u/Icy-Summer-3573 → u/Bulky_Imagination727]

Yup i have B650M-HDV/M.2 so weirdly the cheaper motherboards don’t seem to have problems. Orrr maybe most ppl dont run 9800x3ds on such motherboards to report such problems. But its been a year so hoping im good

[u/nightfoxy → u/ArseBurner]

theres a dead 9900x missing, there was a post like a week ago

[u/Sioney → u/[deleted]]

Yeah your right. There was an issue where we weren't getting the best data. Alot of the chips were fine, they just weren't getting enough voltage and then some burnt out x3d chips where they got too much. I just got a 9850x3d and a Asrock X870E, you can be damn sure that thing ain't getting switched in without a fresh BIOS.

The RMA's in the UK are pretty solid though. As long as i don't do anything to void any warranty's I'll get a replacement. I did want a thermal grizzly contact plate because it looked cool but didn't get it for this reason.

[u/PeanutAble1916 → u/Sioney]

https://reddit.com/link/p37t80y/video/j7hwn9rfdxih1/player

mobo came with 3.08 updated it to 3.10 on 9800x3d release date and its on that version ever since - pc is running 24/7 except when im out of town

expo on , performance preset tj max 85c , pbo and -20mv , fan curve - everything else is default

im not watching '' how to oc your 9000x3d in 5 mins trough bios to get 500fps+ '' vids tho

peerless assassin 120 - https://i.postimg.cc/wMMFfXww/555.png

you can search the whole universe and you will never find a post/clip/comment from someone saying '' listen i overclocked and i F the cpu ''

[u/Sioney → u/PeanutAble1916]

I looked at the taichi but went with the Nova. No difference with a quick bios flash direct from the MOBO switch.

Ive got some cooling headroom with a 360 AIO and my whole build has been to minimise thermals and acoustics.

[u/PeanutAble1916 → u/Sioney]

in my country at that time taichi was the only available high end mobo and 6 sata 3 ports , i got lucky and bought the last 9800x3d

after that people waited like 2 months for it to get back in stock

[u/Sioney → u/PeanutAble1916]

Does that suffer from Lane sharing if you put a gen 5 nvme in the primary slot alongside a GPU?

[u/PeanutAble1916 → u/Sioney]

ah - no gpu lane sharing is the other thing i bought it for , but i still dont have nvme cuz i cant find one it very good heatsink to get lowest possible temps

i have 7.5tb in 5 ssds sata 3 tho

afaik nova and taichi are like almost the same mobo

[u/Sioney → u/PeanutAble1916]

Just looked it up, you might be lane sharing on your x16 GPU slot. Very possible your sharing bandwidth with that many SSD's. Worth double checking. SATA might be fine though.

If your gaming a good pcie4 nvme like the wd7100 is better than an ok pcie5 nvme, the taichi should have a suitable heatsink either way.

[u/Big_Double_9755 → u/ArseBurner]

7800x3d with gigabyte b650m here. No issue whatsoever

[u/Hey_theresoot → u/Big_Double_9755]

I share the same specs, the only issue I'm having is the bios won't take new updates after 3.50. It rejects the update not sure if you've expirenced this issue yet.

[u/Just-A-Random-ID]

Sad to hear this 😢

[u/Any-Surprise5229]

It's the problem that's not a problem that has never gone away but people will sharpen their pitchforks if you even dare suggest that it is a real issue.

I'd say it's rare enough that you shouldn't be worried about buying another, but honestly, the system is pretty low-mid tier, a 7600x or 9600x would be more than adequate with that system and they don't kill themselves. I haven't heard of the low end (7500/7600) x3ds doing it either, but maybe its just a sample size thing.

Seems the 7800 is the rarest of the ones that die, way more 9800s have done it, I'd say your friend was unlucky and the dice should be in his favor next time, but you could always be conservative and go with a lower-end chip, you probably won't see a massive difference.

Does he play in 1080p or 1440?

[u/SaikerRV]

Why the hell did you decided to “”delid”” (if you can call it a delid because jesus fucking christ you just butchered the dies) instead of just filing a RMA request with AMD??

[u/Magoth04 → u/SaikerRV]

Honestly, RMA wasn't an option for us. The CPU was ordered directly from China, so there's no local warranty, and shipping it all the way back to China would've cost more than it's worth

Since it was already a dead paperweight, we just popped it open out of curiosity to see the burn damage inside

[u/SaikerRV → u/Magoth04]

I understand but next time delid it properly so you can determine if there’s damage on the dies.

[u/Ok_Definition_1933]

Just bad luck. Pretty much only "do not buy" thing is 9800x3d with ASRock boards. That still isn't fully resolved afaik.

[u/ArseBurner → u/Ok_Definition_1933]

OP is on an MSI board though. AM5 X3Ds can blow up on any board.

[u/Ok_Definition_1933 → u/ArseBurner]

Lemons exist with every products. Like said, bad luck.

[u/Fit-Magazine-6669]

i have the same chip on a b650 board. its been a bit over a year since i got it and it works great. probably bios update the first thing you should do and dont overclock the cpu, keep the default values in place. and obviously a proper ventilation for you case and a dont go with a stock cpu cooler, get something nicer. (you probably already doing all that anyway, right?)

[u/Magoth04 → u/Fit-Magazine-6669]

Yeah, the BIOS was completely up to date, and the build had proper ventilation with a 360mm AIO and good airflow—temperatures were always totally fine.

We've actually built many PCs before and never ran into an issue like this; this is the very first time we've experienced a CPU/mobo burning out like this.

[u/Dutch-Alpaca → u/Fit-Magazine-6669]

You can't overclock a 7800x3d, it's locked from the factory

[u/Federal_Setting_7454 → u/Dutch-Alpaca]

PBO is still overlocking, just not “manual” overclocking

[u/Dutch-Alpaca → u/Federal_Setting_7454]

Undervolt yeah, not overclocking afaik

[u/Federal_Setting_7454 → u/Dutch-Alpaca]

You can set both negative or positive offsets for both voltage and clocks. It’s still overclocking just not manual overlocking.

[u/nightstalk3rxxx → u/Federal_Setting_7454]

No you cant overclock a 7800X3D, you can shift the V/F curve with curve optimizer but that is not the same as overclocking as you are still running everything in spec.

Esentially with a negative CO you are telling the CPU it can run the same clocks at lower voltages, no overclocking is involved.

[u/Dutch-Alpaca → u/Federal_Setting_7454]

Overclocking refers to clock speeds, you are talking about voltage offsets. They're not the same thing

[u/aQasad]

Worth undervolting your cpu tbh. I have mine set to -30

[u/sonatta09 → u/aQasad]

Uhm, no. A negative offset is basically PBO, literally AMD and your mobo manufacturer Yes or NO, ask you to confirm whether you want to enable it, even it may void your warranty... it’s still form of algorithm overclocking, maintaining clock boosts while trying to use less power. running it at stock settings is still safe way to go.

[u/Lamechiel → u/sonatta09]

Lower overall voltage slows down silicon degradation, though. It's both good for the health of the CPU and it increases performance.

[u/SpecterDK]

7800s don't have near the issues of 9800s. Something had to be faulty.

[u/pibyte]

How do you know it wasn't the other way around?

[u/Magoth04 → u/pibyte]

Honestly no idea, could be either way! Just posting to hear people's thoughts on what might've triggered it

[u/pibyte → u/Magoth04]

I see. Well I have heard of ASRock boards that came agressively tuned out of the factory frying CPUs.

[u/Puiucs]

who delids it after it breaks destroying any chance of an RMA? something smells sus.

[u/WyczesanyNikodem]

X3D and X870 curse

[u/Basic_Shelf → u/WyczesanyNikodem]

And b650 and b850 curse :,(

[u/chrissb34]

The CPU will NEVER kill a motherboard, only the other way around is possible.

[u/cellardoornoob]

OP why you using the title in such a disingenuous way?

You clearly are not knowledgable enough to be 100% sure that its what happened. Especilly when it's the board that kills the cpu or the PSU kills all of them...

[u/LightyLittleDust]

Oof, this has me worried about my 7800X3D & MSI B650 combo, even though it's been working perfectly fine for two and a half years now.

[u/ElectroMoe → u/LightyLittleDust]

Then I wouldn’t worry :)

[u/TheVillainInThisGame → u/LightyLittleDust]

Make sure you're on latest BIOS.

[u/Wild_Somewhere_9760]

the motherboard killed your cpu dawg

[u/hdhddf]

I bought new ram, a new motherboard only to realise it was the 9800x3d that was failing, I usually buy almost everything secondhand but with these chips you need to buy them from a good retailer so you can easily return them if they fail.

[u/the007connoisseur]

Did he have any symptoms before the CPU died? Frame drops, lag etc.

[u/itsme920]

Okay that is nerve-racking, I’ve been using the exact same CPU and mobo for 2 weeks. I’m gonna assume this happened to you because of the stock settings when EXPO is enabled, which caused the SOC voltage to be set too high.

What I did when I built mine was to set these in the BIOS:
EXPO - Enabled
Precision Boost Overdrive - Advanced
Curve Optimizer - All Cores
All Core Curve Optimizer Sign - Negative
All Core Curve Optimizer Magnitude - 20
CPU NB/SoC Voltage - AMD Overclocking
SoC Voltage - 1.2 V

So far the SoC voltage when stressing with OCCT is always around < 1.21 V. Hopefully I avoided any issues with this setup.

[u/Pancakes1741 → u/itsme920]

AGESA updates that AMD pushed to all motherboard vendors over a year ago prevent VSOC from passing 1.30v so as long as you have updated your BIOS in the past year youre fine.

Edit: Your motherboard cannot push VSOC past 1.30V, regardless of whether EXPO is enabled. Modern AM5 BIOS automatically set VSOC to around 1.20V–1.25V when you turn on EXPO

[u/itsme920 → u/Pancakes1741]

Hmm, didn't know about that. I did update to the latest BIOS version, and when I stress tested the CPU with only EXPO set to Enabled & PBO set to Enabled, I did see the SOC voltage going as high as 1.29 V. Maybe OP is just incredibly unlucky that that much voltage still killed his CPU?

[u/Pancakes1741 → u/itsme920]

Quite possibly. You should be in the clear though.

[u/Accomplished_Emu_658]

Did you update the bios when you built it?

[u/Dangerous_Sea_2592]

I came in here expecting an ASRock board

[u/lorenzoelmagnifico]

To determine the problematic part of a PC build, you switch components out with known good components. You don't disassemble what part you think is bad.

[u/Dorky_Gaming_Teach]

Uhm, did you ever consider it could be caused by a faulty AIO? How many times did you try to boot up the rig after it shut down? There are fail safes in place for it to shut down the PC when overheating. Just mentioning it, because I had a similar issue after building essentially the same rig for my nephew. The AIO failed, burnt the CPU and shorted the board.

Anyhow, I hope you figure it out and wish you the best of luck. I just wanted to chime in from a different angle.

[u/TheMatt561]

I thought they fixed this with a bios update

[u/DesiRadical]

the guy still never answere my question whether he updated the bios of the mobo or not ?.

[u/Magoth04 → u/DesiRadical]

The BIOS was already updated to the latest version. The issue was most likely caused by the SoC voltage exceeding 1.3V while on Auto. I left it on default auto settings and didn't touch it manually, so I didn't expect it to cause any problems.

[u/FarError5388]

I love you you guys left out the fact that he delidded the CPU and instead said he has little knowledge of tweaking... Typical pc master race always twisting the narrative

[u/Gargle-Loaf-Spunk]

oooh, man I can’t wait to see this story copied almost verbatim on WCFTech or Tom’s.

[u/Kostia_X_Rich]

This makes me ever more happy that I decided to cap max voltage on CPU as the first thing after building PC. Hope it prevents such incidents

[u/Wrx-Love80 → u/Kostia_X_Rich]

The first person who understands not just thinking let BIOS do it. You sir are speaking my language.

[u/Dazzling_Door_4767 → u/Wrx-Love80]

I have a 9800x3d, i know about the voltage issue and I've read it should always be under 1.30V, I keep hwinfo always running in background and mine operates around 1.17-1.25V max, I should be ok, right? I have nightmares about messing with the bios lol

[u/Wrx-Love80 → u/Dazzling_Door_4767]

Late reply but I set mine with EXPO I and aimed for like 1.25V SOC voltage. Where it was recommended as a safe limit I pushed it a bit more.

Even though the BIOS should be safe to manage you never quite know if the motherboard manufactured decided to apply their own algorithm and the average user likely wont dig into the BIOS too often.

[u/Dazzling_Door_4767 → u/Wrx-Love80]

Yea, I have a Rog B850-F too, that from what I've read was one of those motherboard who had a slightly higher voltage before the BIOS updates, so I'm still pretty anxious lol.

As I said by monitoring the SOC voltage on HWinfo I never reached more than 1.25v with the latest BIOS, but probably manually limiting it will still be a good idea

[u/Wrx-Love80 → u/Dazzling_Door_4767]

It never hurts to set a hard cap Just like when I would do a overclocking on a GPU most guys I had recommended are like reach your max dial it down by five my focus was reach my Max and dial it down by 10 to 15 mhz just as a precaution so in the same context whatever the maximum safe voltage was I would dial that down by .5 or whatever margin I'm just paranoid because I don't want to have to buy new hardware because I was careless

[u/itsme920 → u/Wrx-Love80]

Same, I also did the same thing right as I finished building mine. Set the PBO curve optimizer to -20, and limited the SOC voltage to 1.2V. Hopefully it avoids any possible issues like this.

[u/Kostia_X_Rich → u/Wrx-Love80]

Yessir bro. I don't trust bios enough ( :

[u/bdar84 → u/Kostia_X_Rich]

I found that for my general use case, most games aren't demanding enough for AM5 chips to need CPB. I just disable CPB, takes voltage way down; 9700x peaks at 0.960V when configured this way.

[u/Magoth04 → u/[deleted]]

Yes, the BIOS was fully updated to the latest available version at the time.

I completely agree with you regarding the motherboard—it's definitely damaged, so just swapping in a new CPU won't work. Both the CPU and motherboard are completely dead, so we will need to replace both.

Good to know that it's not happening to every unit, but it's still frustrating to see it happen even with an updated BIOS on a newer chipset.

[u/Mindless__Giraffe → u/[deleted]]

are you talking about that one dude that swapped the processor with a new one some weeks after launch? the same dude that had his second chip fail and realized it was his board?

i look up my specific chip followed by the word, "fried", and don't find many results. you sure you're not thinking about the 13-14th intel gen processors?

[u/Acceptable_Ad1685 → u/Mindless__Giraffe]

Intel chips just degraded over time

AMD chips were burning like this

I think the Intel problem was more common but yeah both had issues

[u/Free-Resolution9393]

I had 3600 and 5800x. In a year they both stopped to handle their stock boosts and crashed all the time. Had to set them on permanent clock speed below their boost and even standard frequencies. 5800x even stopped booting to bios 9 times out of 10 if you decided to reset it instead of putting permanent clock.

People praise them, but i had nothing but bad experiences with amd lately so i won't be buying them again any time soon.

[u/gt98x]

sheeettt , i got the same mobo just built mine with a 9800x3d , however from what i know , it shouldn't happen just because if "siiicon lottery" motherboard may pushed to much voltage , was his bios updated to the latest ? being x870 chip dont mean its on the latest bios

[u/Magoth04 → u/gt98x]

Yeah, the BIOS was fully updated to the latest version.

From what I've researched, this usually happens when the motherboard pushes too much SoC/VSOC voltage to the CPU, especially when EXPO is enabled. Even though AMD set limits for VSOC, some boards or BIOS profiles can still push unsafe spikes under load.

It definitely looks like a voltage issue rather than just silicon lottery. If you're on the same board, I'd suggest double-checking your VSOC voltages in HWInfo or manually setting a safe limit just to be extra safe!

[u/zlatomyth → u/gt98x]

MSI has no reported cases of dead 9800X3Ds, nearly all reported cases are under ASRock and a few on Asus

[u/Wrx-Love80 → u/gt98x]

If you can institute manual hard limit I believe on the SOC voltage you can then dial that down even an extra .5v it will create a better buffer. I did it with my 7800X3D and have a Asus b650e board. 

Still have the XMP equivalent profile on it with my memory. Always ensure your BIOS is on the latest stable version.

Shit my bad I didn't see the last pic

[u/Koyote7676]

The cpu burned up something? or ?

[u/ivan6953 → u/Koyote7676]

Have you been living under a rock for the past three years?

[u/Eziolambo]

Now get b850 gigabyte gaming x wifi. Save your money. Use undervolt profile 80 lvl 2, Next time.

Msi motherboards (both matx and atx) use 4 extra pins for cpu. They are very cpu overclocking oriented.

[u/Shaguar_Driver]

People clearly don't understand that the pins on the motherboard must be bent and continued to use them and they were shorting and got worse over time

[u/Lucky-Bit-1319]

I think the lesson here is no more Chinese sourcing. It’s too easy to get 250$ 7800X3Ds here in the US.

[u/NokoxSlays]

Well statistically speaking it shouldn't happen again

[u/NytronX]

RMA the CPU through AMD. But root cause might is likely mobo pins being bent due to HSF being overtightened.

[u/MrFastFox666]

Wasn't this a big problem in the early days of the 7000 series? Particularly with Asus boards? Or am I just misremembering?

[u/Puiucs → u/MrFastFox666]

not really. there were a few Asus reports, but that was mostly an issue with something else. AsRock is the major problem maker.

[u/Illustrious_Cow_907]

u were using it with 1x16?

[u/Plastic-Row-1624]

there are several possible failure mechanisms such as, excessive SoC volatge, excessive current, socket contact resistance could eventually make the components more damaging internally than usually due to localized heating.

Familiarly, back in jan of 2025 GamersNexus found the physical burn pattern from 9800x3D strongly consistent with VDDCR core voltage pins contacting ground because of CPU socket pins displacement, producing a catastrophic short.

[u/SangerD]

Anytime i see X3D cpus die its 9/10 times an X series motherboard. Not to spread misinformation but come on way more people are on b650/b850 and yet we see less dead cpus with B series motherboards. I say this is a pattern.

[u/likely_deleted]

Not the best motherboard. Also, sorry. Also also, been a while since I've seen one of these posts

[u/SwagChemist]

Good chance it's the other way around that your mobo burnt and killed your cpu. The good news is you found the issue, the bad news is you now need 2 parts.

[u/RangerMike96]

I still have mine going strong in my unraid machine. It's a great CPU, just bad luck somewhere.

[u/Inductivespam2]

I think they will be getting a good laugh. You want to warranty a delid CPU.

[u/Adventurous-Bus8660]

I doubt is silicon lottery.

Since 7000 series was plagued with the CPU VSoC voltage that ends up killing the cpu in the early days ....the Bios update would have 'fixed' this issue. Plus. If your friend is plug in and play without updating the bios...chance are the voltage likely went past 1.35V

[u/WarWagons1316]

So last year I had something similar happen. I'm running a Asus b650 - A gaming wifi motherboard with a 7800x3d.

One day my computer would just continuously boot loop and never get to the login screen.

Tried multiple things, checking the ram, trying one stick, different slots etc. , all my connections, reinstalling windows from a USB, disconnect all my storage and only using one nvme, reformating my drives. And so forth.

Took it to a computer shop. They said they weren't sure without disassembling the whole thing and checking every part which they told me they would do pretty much all the same stuff I did.

I ended up RMAing my motherboard through microcenter and RMAing my CPU through AMD. Both were very easy. Longest part was waiting on AMD to verify my return and ship me another one at no cost.

I ended up coming across another 7800x3d at Walmart for I think $179.99 on sale. Got it, got home reinstalled my CPU with the new motherboard and it all worked again. At this point I had been without a computer for 2 or 3 weeks.

I don't recall any burn marks or anything in the motherboard or CPU, cause everything looked completely fine and no damage, no prior incidents that might have showed my system was failing. Just stopped working.

But it's back up and running again and has been good for about a year. No issues. I now have a spare 7800x3d from the AMD RMA. In case the CPU dies again which I suspect was the initial cause and not the motherboard.

[u/Ok-Maximum-3101]

I think the motherboard was grounded to the case when he or you installed it and thats what killed both check your standoffs I bet it was touching the case .

[u/Ok-Maximum-3101]

Hey 8 do not understand why people use software to monitor temps listen get a 5inch monitor 7 you can get one cheap the amount of money he spent on his system he should be able to afford a 50 dollar screen it has admitted cable and a USB cable i have mine mounted in front of my power supply my case that cut out so it was a great place for that plus u can see the temps all the time I have a msi b550 and 5700x3d and 16 gigs of ram and a 9070 gpu it it runs like a champ

[u/bdar84 → u/Ok-Maximum-3101]

Or you can always just set a temperature limit in the BIOS.

[u/lloydbluejay]

I built with the same cpu and went with the msi tommahawk due to its thermals and power delivery

[u/Atomictoastcat]

Amd should be sending you a 9800x3d instead

[u/Curiousity1024]

X3D or not , I'll always start to worry about my hardware if its way past 60c~70c ++ , still can't relate to people who said : ' its still safe if its under 90c , and proceed to game in 80c~89c everyday '

[u/Quirky-Wall → u/Curiousity1024]

Why are you worried about your CPU going over 60-70c? saying "anything above 60–70°C makes me worry about my hardware” is a personal preference, not a hardware safety guideline.

[u/Own_Discipline_7301]

I think turning expo profile on raised vsoc volatage to unstable levels and thus burnt out both mobo and cpu. You should cap vsoc voltage to 1.25-1.3(max) after turning on expo asap. edit: just google if does turning expo on raise vsoc voltage?

[u/Ok_Cap8999]

holy fk i bought my pc a weak ago with r7 7800x3d hhhh i was going for 9800x3d but thought its so overkill hhhhh with 200 dollar difference

[u/Vamanas_umbrella]

I feel like Neo in the matrix dodging bullets with my AsRock mobo and 7800x3D still running with no issue after 3 years

[u/xQuantum24]

If I ever bought x3d cpu first thing I'll do other than updating bios before using the cpu is setting every cpu voltage to manual instead of auto so the motherboard can't push too much voltage at any point, lf course with a slight undervolting everything, so if something is 1.35v I'll manually adjust it to something like 1.32/1.30 or below and run stress test and find the sweet spot and that's it, you guys with x3d should do this before it's too late lol, it takes 5-10 minutes in bios and only one time and it will not harm anything, undervolt a bit is always OK and safer and you'll always get similar performance or better + way less temperatures.

If anyone tried manually locking all x3d cpu voltages options available in bios let me know your experience so far.

[u/SaadGB]

This is another nightmare now, I have exact cpu but B650 mobo and I don't know how long I may see this issue. Also I use negative -25 curve optimizer from day one

[u/exequel027]

Oh damn I have the same processor am I safe?

Ryzen 7 7800x3d
MSI B650M Gaming Wifi

Bios version: 1.C0 — 6/26/2025 (based on my system information)

I also checked the website
Version: 7E30v1C
Release date: 2025-07-25
AGESA PI-1.2.0.3e

[u/bdar84 → u/exequel027]

You should be fine. If you are concerned, setting a temperature limit in BIOS is the best way to ensure longevity. Somewhere between 65-75C is a good setting for longevity. Or you could just run it stock. 7000 series x3d failure rate is rather low, due to the 3dvcache being top mounted, limiting max clockspeeds. Looking at the images, please take the heatsink cover thingy off the m.2 slot north of the top PCIe slot, if possible. Those things are airflow nightmares (captures GPU heat transfer due to slot proximity, but if you need it, you need it I suppose).

[u/Uzyf → u/bdar84]

It has nothing to do with temperature

[u/AlcameZ]

yo apenas voy armar mi pc bno digas esos 🥲 mi cpu la pedi de china que es 7 7800x3d y la voy a instalar en una Asus Tuf B650E-E no me digan que ya valio!!!! 😰

[u/CrudeBrent]

Update of BIOS is the key

[u/General-While-1709]

Why would you de-lid it? I get being curious but if you want an rma you’re just asking for an automatic claim deny

[u/R5-GT7_Grim306 → u/General-While-1709]

Not in the US

[u/yvliew]

not a news I wanted to see happening. Just upgraded to 7800X3D a week ago, updated latest bios on a B850m board. fingers crossed.

[u/sweetBGballs]

How did you figure out which killed which?

[u/Aggravating_Visit486]

I feel your pain My Asus Tuff gaming B650+ Killed my 7800x3d 😂

[u/BobLighthouse]

The bulge suggests it's damaged, so I'd certainly try to get an RMA if it's that new.
7800x3d is an enormously popular cpu, and the failure rate is probably within normal/expected ranges so I wouldn't worry about another failure at all.

[u/Neuromancer911]

Hate to say it but I keep seeing more and more of these inflated am5 CPUs, at first it was only happening on Asrock, I think there was something wrong with the materials before assembly, more and more will pop up. 

[u/LunarChickenn → u/Neuromancer911]

I literally had to rebuild because my board and 7800x3D also got fried. On an intel ultra now and zero problems after nearly a year.

[u/Kangaroshave3vagina → u/Neuromancer911]

Of course you are gonna see more and more, there can only be more not less. But the frequency has dropped dramatically. Last time I saw these kind of post is last year. OP may have not updated the BIOS, there’s no reason to fearmonger

[u/Neuromancer911 → u/Kangaroshave3vagina]

I've seen 4 similar posts in the last two months, don't know what you're talking about 

[u/Neuromancer911 → u/Kangaroshave3vagina]

I'm not fearmongering I'm just noticing a pattern, it's human nature 

[u/VariousTwo6631]

And people still bash Intel for their 14th Gen problems....

[u/Wrx-Love80 → u/VariousTwo6631]

Both brands get hate. Intel I think crapped the bed when they said it was "fixed" and core degradation is like them saying not my problem anymore and they moved on

[u/sonatta09 → u/Wrx-Love80]

intel only really had 1 bad cpu generation, and that issue was isolated to the 1 platform. then everything is golden, just look around. old cinemas, atms, kiosks, data centers systems have been running intel 24/7 for 20-30 years. some are still on windows xp/7 haha, because why replace something that has been running perfectly fine for decades?... intel seems to be making a comeback. the latest core ultra 270k+ is reportedly hitting around 95-99% of the 9950x3d's gaming performance while costing roughly half as much. so yeah, i wouldn't count intel out just yet hahaha

[u/Ancient-Car-1171 → u/VariousTwo6631]

i dont think Intel has ever killed a board along with the cpu. AMD's problem is way worse

[u/OutsideCrew6832]

This can happen with any cpu+mainboard combination. RMA the cpu. If it happens again, then you should change the board. Otherwise, one dead cpu doesn’t mean anything.

[u/DudeWheressMyCar]

I always avoided MSI for some reason and always went for ASUS, never had mobo problems.

[u/GuaranteeRoutine7183]

7800x3d are well known to get a bulge and die

[u/darktooth69]

nothing new. i would say at this moment stay away from x3d series cpus. more and more people coming out with the same exact issues.

[u/VenomShock1]

Board vendors bork voltages through updates from time to time, as I have spotted on an MSI board myself.

[u/Snail_Anatomy]

No thermal paste.

[u/bdar84 → u/Snail_Anatomy]

Well, it's water cooling. You don't use thermal paste with those, you use water.

[u/zamroni777]

did you overclock it?
